This invention relates to a process for pro viding tubes or articles of solid cross-section of any desired material with a covering of wood.

The process is illustrated in the accompanying drawing, in which Figure 1 shows the rolling of a veneer on a tube, and Fig. 2 the securing. of the same by drawing through a draw plate.

The process consists in very fine or thin veneer a being coated on the back with a glue, and in winding the said veneer, for instance, on a steel tube 6 and thereupon drawing the said tube through a suitably heated draw plate 0. The appearance of the steel Specification of Letters Patent.

tube cannot then be distinguished from that of a Wooden tube, and such tubes can be used for various purposes, such as for instance umbrella sticks, insulating tubes, and so forth.

What I claim as my invention and desire to secure by Letters Patent is 1. A process for manufacturing composite articles consisting in coating a core with veneer lates and passing the whole through a heated draw-plate.

2. A process for manufacturing composite articles consisting in coating thin wooden plates with glue, Winding said plates upon a metal core and finally passing the whole through a heated draw-plate.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
